I suggest you ...

Allow lists to be posted as public and searchable by name rather than having to explicitly share the list with people.

We have a large family and I don’t necessarily have everyone’s contact info and even if I did, I really would rather not send an email to the world inviting them to view all the things I want. It would be nice if someone wanted to buy me something they could just search for my name. Even money apps allow you to do that.
